808 Mr. O. E. Janson on the genus 



tonkincnsis, Moser (Berl. Ent. Zeit., 1901, p. 525), must 

 also be referred to this genus, but judging from the 

 description the latter is apparently identical with rasuta, 

 Fairm., in which case the genus would now comprise five 

 species, all of which are known to me. 



Ingrisma binghami, n. sp. 

 Cyanea vel viridis, nitida, coxis posticis marginibus pediljusque 

 rufis, tarsis rufo-piceis, elytris striato-pinictatis. 



(^ . cljpeo elongate, medio constricto, apice valde dilatato, margine 



antico medio late reflexo ; tibiis anticis tenuoribus, lateribus 



inermibus. Long. 30 mm. 

 9 . clypeo piceo, apice leviter dilatato, rotuiidato ; tibiis anticis 



brevioribns, latioribus, lateribus apiceque valde dentatis. 



Long. 26 mm. 

 Tenasserim. 



Deep purple blue, or green with a reddish-golden tint in certain 

 lights, the sides of the head and thorax, the base of the pygidium 

 and the abdomen slightly rufescent, the hind margin and exposed 

 upper-side of the meta-coxse, sides of the abdomen and the legs red, 

 the femora tinged with blue or green, the knees, extreme apex of the 

 tibiaj and the tarsi reddish piceous ; in the female the anterior part 

 of the clypeus is also piceous. The whole of the upper surface and 

 the abdomen have a very fine and dense punctuation, which is only 

 discernible under a lens. 



Head rugosely punctured, the base smooth, clypeus strongly 

 constricted aboiit the middle and very much dilated in front, the 

 side margins strongly elevated and acute, strigose on the outer side, 

 the apex broadly reflexed with the entire apical margin strongly and 

 uniformly rounded. Thorax a little rounded at the sides and 

 narrowed from the base, the basal margin distinctly emarginate 

 above the scutellum and with the lateral angles rounded, finely and 

 sparsely punctured on the disk and at the base, more strongly 

 punctured towards the sides. Scutellum broad and triangular, 

 remotely punctured. Elytra broader than the thorax at the base, 

 the disk obsoletely bicostate and with rows of coarse semi-circular 

 punctures, five of which are regular and continuate, the others 

 being irregular, the sides more finely and irregularly punctured, and 

 strigose towards the apex, the sutural angles almost right angles. 

 Pygidium very finely and closely strigose, slightly impressed on 

 each side near the apex. Beneath coarsely strigose at the sides : 

 mesosternal process long, broad and flattened, obliquely divergent 

 and slightly curved, its apex rounded ; anterior tibije slender and
